Electronic structure and correlations of vitamin B12 studied within the Haldane-Anderson impurity model [PDF]

, 2015
We study the electronic structure and correlations of vitamin B12 (cyanocobalamine) by using the framework of the multi-orbital single-impurity Haldane-Anderson model of a transition-metal impurity in a semiconductor host. The parameters of the effective

Sinorhizobium meliloti requires a cobalamin-dependent ribonucleotide reductase for symbiosis with its plant host [PDF]

, 2010
Vitamin B[subscript 12] (cobalamin) is a critical cofactor for animals and protists, yet its biosynthesis is limited to prokaryotes. We previously showed that the symbiotic nitrogen-fixing alphaproteobacterium Sinorhizobium meliloti requires cobalamin to

EVALUATION OF ANTIBIOTIC RESISTANCE PROFILES OF HALOBACTERIA ISOLATED FROM THE FOOD CHAIN [PDF]

, 2017
L’insorgenza e la diffusione dell’antibiotico resistenza sta diventando un problema a livello mondiale. Molti sono gli ambienti in cui può avvenire tale diffusione, ma una delle principali vie di trasmissione passa attraverso la catena alimentare ...
